Title: An apparatus for handling stacks of paper
IPC: B65H31/30
Filed: 1965-03-10
Abstract: 1,046,134. Freight handling stations. KONINKLIJKE NEDERLANDSCHE PAPIERFABRIEK N.V. March 10, 1965 [March 12, 1964], No. 10203/65. Heading B8E. A stack 5 of sheets, located in contact with guides 6, 7 on a stationary table 4 with the leading edge 8 overhanging the table, is transferred on to a trolley 1, running on rails 3, by a clamp device 11 which is mounted on the trolley and which is moved down to clamp the edge 8 of the stack to the trolley. On moving the trolley to the left, the stack is pulled on to the trolley. The clamp device 11 is then raised a stop member 13 is lowered, Fig. 2 (not shown), and the trolley is reversed, whereby the stop member pushes the stack to the left of the trolley as the trolley returns to its initial position to receive a further stack 5<SP>1</SP>. As the clamp device 11 then descends to engage the stack 5<SP>1</SP>, a clamp device 12 descends on to the stack 5 and the stop 13 rises.

Title: Improvements in and relating to microscopes
IPC: H04N7/18
Filed: 1951-05-01
Abstract: 707,406. Local viewing. YOUNG, J. Z., ROBERTS, F. F. W., and CAUSLEY, D. J. April 30, 1952 [May 1, 1951], No. 10233/51. Class 40 (3) A system for producing upon the screen of a cathode-ray tube 17 a magnified image of an object comprises a cathode-ray tube 11 having a scanning raster formed on its fluorescent screen 10, a microscope 12 so disposed and adjusted that light entering the eye-piece from the fluorescent screen 10 is brought by the microscope objective to a real, diminished image in the plane of a slide 13 carrying the object, and a photocell 14 upon which light passing through the slide 13 is incident. Thus the object is scanned by a diminished image of the raster upon the screen 10 and by applying the output of the photocell 14, through an amplifier 16, to the control grid of the cathode-ray tube 17, the electron beam in which is deflected in synchronism with the beam in the tube 11, a magnified image is produced upon the screen of the tube 17. In the present invention, in order to produce adequate resolution at large magnifications (of the order of 4,000 to 5,000) the reduction in the diameter of the scanning spot is made such that the theoretical diameter of the spot image (i.e. its diameter calculated on geometrical-optical principles) does not exceed one-tenth of the wavelength of the light forming the scanning spot and is preferably of the order of one-hundredth of that wavelength. The screen of the cathode-ray tube 10 preferably has a very short afterglow, e.g. of the order of one-tenth microsecond. The amplifier 16 is given a gain-frequency characteristic which compensates for aberrations in the optical part of the system ; this characteristic may also be made to compensate for the finite afterglow time of the screen 10. In order to improve the signalto-noise ratio the screen of the cathode-ray tube 17 is preferably of the long afterglow type. An illusion of stereoscopy may be produced by employing two scanning tubes 11 and two microscopes 12 used alternatively at the frame frequency and forming images of their respective rasters in slightly different planes in the object. A phase-contrast microscope may be interposed between the object and the photocell 14, in order to produce a phase-contrast representation of the object upon the screen of the cathode-ray tube 17. The system may be used to produce ultraviolet or infra-red images of the object.

Patent GB-498973-A (GB)
Title: A process for the production of unsaturated ketones
IPC: C07C45/66
Filed: 1938-04-05
Abstract: Unsaturated ketones, such as mesityl oxide, are produced by the catalytic dehydration of the corresponding keto-alcohols, such as diacetone alcohol, an overhead product containing a ratio of unsaturated ketone to water which is greater than that prevailing in the corresponding binary azeotrope being continuously distilled from the reaction zone.  This result is attained by using as reflux medium a mixture of unsaturated ketone and water possessing a molecular ratio of unsaturated ketone to water greater than one and preferably greater than that prevailing in the distillate.  A part of the stratified unsaturated ketone phase, obtained by condensation of the distillate, may be used as refluxing medium.  A still-head temperature above the boiling temperature of the binary unsaturated ketone-water azeotrope is maintained, which in the production of mesityl oxide is preferably not substantially less than 110 DEG  C. Sodium bisulphate may be used as catalyst and the keto-alcohol may be introduced as a vapour continuously.  Methyl vinyl ketone may be obtained from 3-hydroxybutanone-2, methyl allyl ketone from 4-hydroxypentanone-2, methyl isopropyl ketone from 3-methyl-4-hydroxy-butanone-2, 3-methyl-pentene-3-one-2 from p 3-methyl-4-hydroxy-pentanone-3, 5-methyl-hexene-4-one-2 from 5-methyl-4-hydroxy-hexanone-2, 3-ethyl-pentene-3-one-2 from 3-ethyl-4-hydroxy-pentanone-2, diisobutenyl ketone from 2,6-dimethyl-2,6-dihydroxy - heptanone - 4, 2 - hydroxymethyl - butene-3-one-2 from a , a -dimethylol acetone, 3 - methyl - heptene - 3 - one -5 from 3 - methyl-3-hydroxy-heptanone-5, 2,5-dimethylene-cyclohexanone from 2,5-dimethylol-cyclohexanone and the corresponding unsaturated ketones from homologues, analogues and substitution products of such ketols.

Title: Improvements in or related to power drives for paper-making machines or other plant comprising a number of inter-related sections
IPC: D21F7/02
Filed: 1921-04-09
Abstract: 182,579. Evans, A. J., and Richards, A. April 9, 1921. Driving -mechanism.-A power drive for the inter-related sections of a machine or machine plant, such as paper-making machinery, has means for synchronizing the master shaft with each individual motor. A separate motor drives each section such as E, and drives also a master shaft F through cone pulleys C, G, and a belt O. The cone pulley G, which is free on and may be clutched to the shaft F, carries a small belt pulley adjacent to a belt pulley K fixed on the master shaft F. From the pulleys, belts or chains P, P1 drive co-axial vertical shafts R, S, carrying speed-indicators comprising two plates J2, K2 having the same number of spokes, forming visual means for determining when the master shaft and the cone pulley G are running at the same speed. In operation, the first motor is started, and its cone pulley G clutched to the master shaft F. The motor of the second section is then started, and when the plates J2, E2 indicate that the pulley G of the second section and the master shaft are running at the same speed, this cone pulley G is clutched to the master shaft. This method is followed with all the sections successively. Adjustment of the speed of cone pulleys G is effected by the belt-shifting mechanism L, M. The motors may have their shafts parallel, and the cone pulleys C may be clutched thereon and the speed indicators J2, K2 may be driven direct from their respective motor shafts. In the arrangement shown in Fig. 3, having the motor shafts parallel, each motor a drives its section through gearing c. Double coned pulleys d, d1 arranged alternately with their small ends together and their large ends together, are connected by belts g and the master shaft F thus dispensed with. The indicators J2, K2 are driven from the small pulleys e, e1, f, f1, respectively fixed on the motor shaft and on the double-coned pulleys.

Abstract: 570,927. Regulating pressure of fluids. GRANT, C. R. A. June 29, 1943, Nos. 10553/43 and 1146/44. [Class 135] [Also in Group XIX] A pressure gauge provided with a pulsation damping device comprising a rod 9, or a number of rod sections arranged end to end, movable longitudinally with a slight clearance and within predetermined limits in a passage 1 located in advance of the pressure - responsive element, such as a Bourdon tube 4, has slots 10 across the ends of the rod, or of the end sections, to allow the fluid to flow into or out of the passage 1 when the rod is in contact with one end of the passage. Springs may be interposed between shoulders on the ends of the rods and the ends of the passage 1 so that the rod is positioned in the central part of the passage when pressure is not being applied. The rod, or some of its sections, and/or the inner surface of the chamber may be provided with a screw-thread. To allow for the difference of viscosity of the fluid at high and low temperatures, the material in which the passage is formed has a low heat coefficient of expansion and the rod has a relatively high coefficient.

Title: Improvements relating to electrolytic apparatus
IPC: C25D7/06
Filed: 1920-04-15
Abstract: 141,733. Merritt, M. M. April 15, 1919, [Convention date]. Roller-conveyer apparatus; electrolytes, circulating and trcating non-chemically; cells; supporting electrodes; preparing surfaces; treating after deposition; moulds; metals, depositing.-In coating a wire or forming a tube, the steel wire or other cathode passes around sheaves 21, 22, Fig. 2, so as to traverse the depositing apparatus repeatedly in opposite directions, while the circulating electrolyte falls from the cell into a tank and is thus aerated. The depositing apparatus may consist of a pair of open-ended troughs 18, sloping downwards from the middle, where the electrolyte enters, to the ends. To facilitate threading of a new wire, the troughs can be raised and lowered between rollers and sliding guides by racks and pinions 27 and a handle 29, a pawl 30 normally arresting the pinions. Within the troughs the parallel lengths of wire may be guided by horizontal glass rollers, supported by a fixed frame independent of the troughs. Anodes may consist of copper sheets or copper scrap held by perforated leaden plates. The tank 19 receiving the falling electrolyte is large enough to allow of the separation of impurities, and may have a heating device to promote the disengagement of hydrogen. Iron or steel wire, before being plated in the troughs 18, may be led through a cleaning tank 9, Fig. 1, containing hydrochloric acid and tin chloride. After being washed by jets 10, the wire is lightly plated in a copper-cyanide bath 11, and is then washed by passage through a glass tube 14, supplied with water by a branch 15. According to the Specification as open to inspection under Sect. 91 (3) (a), a current density exceeding 50 amperes, say 1000 amperes, per sq. ft. may be employed in the main depositing apparatus. Aluminium, before plating with copper, may be freed from oxide and provided with a protecting coating for instance of tin from a solution of hydrochloric acid and tin chloride. This treatment may be effected in the tube 14. which then contains a sponge to prevent rapid flow; the other preliminary operations above described are omitted. In the manufacture of tubes, there is used a cathode of fusible metal such as tin, or tin-lead alloy, or other conductive or conductivelycoated material. No preliminary treatment is essential, but if the cathode contains tin or the like, and is first treated in the cyanide bath, a part of the tin or the like adheres during the subsequent melting out so that a tube tinned &c. internally is obtained. The melting out may be effected in a vertical furnace after the tube has been coiled to a helix, air pressure being applied at the upper end of the tube. The Claims also mention the cleaning of cathodes by steam after deposition. This subject-matter does not appear in the Specification as accepted.

Title: Separation of components from a liquid mixture
IPC: B01D19/00
Filed: 1952-04-26
Abstract: <PICT:0770761/III/1> In a process for the separation of the more volatile components from a liquid mixture, e.g. separating hydrocarbons containing 1 to 4 carbon atoms per molecule from crude petroleum, wherein the pressure on the mixture is decreased in three or more stages, the gas which separates in the first stage is withdrawn from the system, but the gas which separates from at least one of the later stages is compressed and then reunited with the mixture, in such a manner that equilibrium is attained, before the mixture enters a stage operated at a higher pressure than that of the stage from which the gas is withdrawn.  In an example, crude oil containing dissolved light hydrocarbons at a pressure of 30 atm. is passed through line 1 and valve 2 into separator 3 which is maintained at a pressure of 25 atm.  The gas which separates in separator 3 is vented from the system through valved-line 4.  Liquid from separator 3 flows through valve 5 and line 6 into separator 7 which is maintained at a pressure of 5 atm.  The gas released in separator 7 is withdrawn and compressed by compressor 9 to 25 atm.; and the compressed gas is mixed with the liquid in line 1 at a sufficient distance from separator 3 such that equilibrium is attained before the mixture reaches separator 3.  The liquid from separator 7 is passed through line 11 and valve 12 into separator 13 which is maintained at atmospheric pressure.  Gas is withdrawn from separator 13 through line 15 and is compressed to 5 atm. by compressor 16, the compressed gas being then mixed with the liquid in line 6.  Stabilized crude oil is withdrawn from the system through line 14.  In the above process the temperature is maintained at substantially the same level in each of the three stages of the unit; but, if desired, the temperature may differ in one or more stages. Examples are also given of the separation of gases from a C1-C7 + hydrocarbon mixture.

Filed: 1955-04-14
Abstract: 798,786. Controlling steam temperature in boilers. COMBUSTION ENGINEERING Inc. April 14, 1955 [July 28, 1954], No. 10760/55. Class 123(3) In a water-tube steam boiler comprising a furnace 10 lined with steam generating tubes 16 and fired by burners 12, which may be of the tilting type and wherein the combustion gases discharge from the furnace through an outlet 14 into a pass 26 locating a secondary superheater 36 and a reheater 42 and then flow downwardly in a pass 28 in which is disposed a primary superheater 30, the temperature of reheat is controlled at loads below the maximum by suitably regulating the amount of heat absorbed by the tubes 16 either by adjusting the tilt of the burners 12 or by introducing an appropriate flow of cooled flue gas into the furnace through conduits 48 which are connected to the outlet of a fan 54 withdrawing the gas from the bottom of the downpass 28 through a duct 46. At the same time, to maintain the superheat temperature, which perforce, is also altered by operation of the reheat temperature control, at the required value without the use of de-superheating the temperature of the gases entering the primary superheater is raised or lowered as necessary by introducing into the top of the downpass 28 either a flow of gas direct from the furnace through a by-pass 52 whereby the temperature is raised or a flow of cooled flue gas to lower the temperature, the latter flow being conveyed from the fan 54 through a duct 50 controlled by a damper 58. The flow of furnace gas through the by-pass 52 is controlled by a damper 60 which is so arranged that it can also restrict the flow out of the recirculating duct 50. In a modification the positions of the reheater and secondary superheater in the pass 26 are interchanged and an additional duct conveying cooled, recycled gas to a position above the burners 12 is provided.

Title: Improvements in or relating to electric impulse counters

Filed: 1959-03-31
Abstract: 855,468. Counting apparatus. RINGSDORFF-WERKE G.m.b.H. March 31, 1959 [March 27, 1958; Feb. 4, 1959], Nos. 10919/59. Class 106 (1). [Also in Group XXXV] In an electrical impulse counter a multitoothed ferromagnetic rotor 3, connected to a counter mechanism, rotates between the poles of stator cores 1, 2 which have phase-splitting windings 4, 7 connected across input terminals 11 so that on receipt of an impulse, rotor 3 is attracted first to core 1 then to core 2, the complete movement completing one step of the counter. The radial spacing of the pole ends equals that of the extremities of the rotor and the cores are so placed that when the teeth of rotor 3 are opposite the poles of one, the poles of the other face the spaces between the teeth. Winding 4 is in series with capacitor 5, resistance 6 and winding 7 in series with inductor 8 and resistor 9. Core 1, on receipt of a pulse, is energized and the current fluctuates according to graph a (Fig. 2), whilst that in core 2 increases as on e-function (graph b). At a time t 1  when b is small rotor 3 is atrracted by core 1 to make a half-step and at time t 2  when a is zero core 2 attracts the rotor to complete the counting step. As both movements impart acceleration to rotor 3, an eddy current brake 12 (wound of high-conductivity metal) is provided on core 2 to halt the rotor. The brake operates only when core 2 is energized and as it delays the generation of flux in core 2 it can replace inductor 8. At time t 1  the small flux in core 2 which slightly impedes rotor movement may be avoided by passing the current in coil 4 through a compensating coil on the core (Fig. 3, not shown), to produce a field equal and opposite to that produced by coil 7 at time t 1 . At time t 2  the compensating coil has zero current (Fig. 4, not shown).
